George Harris (15 May 1794 – 24 December 1859) was a British Unitarian minister, polemicist and editor.
Born at Maidstone in Kent on 15 May 1794, he was son of Abraham Harris, Unitarian minister at Swansea for 40 years. George was at the age of fourteen placed in a Manchester warehouse in Cheapside, London, but, wishing to enter the Unitarian ministry, he gave up his place. In his eighteenth year he entered the Islington Academy, then under John Evans. In November 1812 he matriculated at Glasgow University, on a bursary from Dr Daniel Williams's trust, and attended classes in Glasgow during three winter sessions. His studies were interrupted by engagements as a preacher and lecturer.
The Scottish Unitarian Association was formed in July 1813. Harris was one of its originators, and was for three years its secretary. He also spent time in establishing Unitarian churches, principally in Paisley, Greenock, and neighbouring towns, and in directing Unitarian stations in different parts of Scotland. In 1816 he issued A Statement of the Principles of Unitarian Christianity addressed to the Inhabitants of Greenock and Port Glasgow, and to the Friends of Free Inquiry throughout Scotland, by a Unitarian[1], a concise manual of Unitarian teaching. By his efforts a Unitarian chapel was erected in Port Glasgow. It was opened by him in January 1822; the sermon which he preached on the occasion was published. At this period he also published Select Pieces for Reading and Recitation.
In April 1817, Harris was invited to become minister of Renshaw Street Unitarian Chapel in Liverpool, then vacant by the resignation of Robert Lewin. He was inducted in July, and his convictions soon engaged him in numerous controversies. Many censured his severe attacks on evangelical doctrine. His pamphlet, Unitarianism, the only Religion which can become Universal, and a course of Sunday evening lectures, published as Unitarianism and Trinitarianism contrasted, called forth replies. Dr. James Barr of Oldham Street Presbyterian Church, Dr. John Stewart of Mount Pleasant Secession Church, and Mr. Jones of St. Andrew's Church were his most prominent opponents. In 1818 Harris planned a Unitarian Christian Association for the dissemination of unitarian literature, and he travelled through Lancashire and Cheshire to gain for it sympathy and support.
